请分析以下程序。 int main() { pid_t pid; pid = fork(); if(pid==0) printf("I am the child process, my process ID is%d\n",getpid()); else printf("I am the parent process, my process ID is%d\n",getpid());} 那么，该程序正确运行后的结果是A.I am the child process, my process ID is 3744 I am the parent process, my process ID is 3987B.I am the child process, my process ID is 3744C.I am the parent process, my process ID is 3987D.不输出任何信息
